-这 5 条是 `spec/` 这份语义母本的定位与约束,是本仓库一切工作的前提。
+这 4 条是本仓库的协作约定,是一切工作的前提。
 
-1. **角色 —— Lean 是研发侧的上游参照。**
-   `spec/` 用 Lean 编写,是开发者(领域专家)与 coding agent **共用**的 spec 工具,用来沉淀产品各部件的**语义**。它**不进入产品运行时**——产品里"站在 Lean 这个位置"的那个 checker 用什么技术实现,尚未决定;但那个东西的语义,先在 `spec/` 里固定下来。
+1. **角色 —— ADR 是决策真相。**
+   跨部件的语义决策只记录在 `docs/adr/`,一份决策一份 ADR,编号顺延、正文不改写历史。代码里的关键不变量用注释锚到 ADR 编号,保持可 grep。没有第二份权威文档。
 
-2. **对齐机制 —— Lean 只做上游参照。**
-   不做 extract / codegen,不派生 conformance test,CI 里**没有** spec→实现的 gate。实现对齐 spec,由"开发者 review + agent 巡逻 diff"这个人肉环节承载。
-   (CI 里的 `spec check` 只验 spec **自身**能否 type-check,即契约内部良构,不是 spec↔实现的对齐检查。)
+2. **对齐机制 —— 人肉承载,无机器兜底。**
+   CI 只验各部件自身良构(build / test / clippy),**没有**决策↔实现的一致性 gate。实现对齐 ADR,由"开发者 review + agent 巡逻 diff"这个人肉环节承载。发现漂移,报告它,不要默默让其中一边将就另一边。
 
-3. **资产性 —— 由 review 纪律承载,无机器兜底。**
-   这份仓库给你的是"精确、自洽、机器验内部良构的语义共识",**不是**"实现正确性保证"。spec 与实现之间那道缝,是我们自愿用人来守的——清醒地守,它就是资产;放任实现漂移而不回头同步,它就退化成最贵的过期文档。
+3. **形态 —— 自包含。**
+   凡 ADR 未明文规定的,开发者与 agent 双方都不该假设;遇到没覆盖的地方,**显式 surface** 出来让开发者决定。
 
-4. **形态 —— 它是人机共识的契约。**
-   契约必须**自包含**:凡契约未明文规定的,开发者与 agent 双方都不该假设。这比"文档"严格——type checker 会逼这份契约在结构上无洞。
-
-5. **深度判据 —— 只收录分歧点。**
-   一条语义该不该写进 Lean,取决于一句话:**"不写明,开发者与 agent 会不会各自做出不同假设?"** 会 → 进契约;显然的东西 / 纯 plumbing / 普通 CRUD 字段 → 不进(写进去只稀释信噪比、增加维护面)。
-   深度上限不是 Lean 的表达力,而是**你愿意在每次实现变更时手动回头同步的量**——写得比你能维护的更深,多出来的部分会率先过期、反过来误导实现。

 ## CI
 
-`.gitea/workflows/spec-check.yml` 在每次 push / PR 时于 `spec/` 下跑 `lake build`,确保契约始终 type-check 通过(从第一天起就是"绿"的)。这是良构 gate,见宪法第 2 条。
-
 Rust checker 的本地与 CI 工具链由根 `rust-toolchain.toml` 固定;`.gitea/workflows/checker-check.yml`
 必须安装同一精确版本并执行 `cargo fmt --all --check`、Clippy `-D warnings` 与 workspace

+# ADR 0027: External Capability Registry
+
+## Status
+
+Accepted.
+
+## Context
+
+ADR-0026 introduced the `UsageFact` ledger with a `kind = external_capability`
+fact and a `capabilityId` field, but deferred the capability registry itself.
+Two concrete needs now force the issue:
+
+- **PDF→Markdown bundle** conversion (and, imminently, audio/video→text)
+  must run as a side effect of an `AgentRun`, bill in non-token units
+  (pages, seconds), use a different provider than the model loop, and report
+  cost through a different channel. It is not a sub-run (ADR-0026 rejected
+  that) and not a model-provider call (it does not speak the Anthropic/
+  OpenRouter protocol).
+- The Agent already has a Bash tool. Without a first-class capability seam,
+  the path of least resistance is for the agent to shell out to ad-hoc
+  scripts that embed API keys, write to arbitrary paths, and report nothing
+  to the ledger. That is exactly the unattributed, uncontained external
+  consumption ADR-0022/0026 exist to prevent.
+
+The model-provider connection (`OrganizationProviderConnection`, ADR-0024)
+is the wrong seam for these services:
+
+- Its payload schema (`baseUrl` + `authToken` + `anthropicApiKey`) and
+  readiness probe (`/v1/models?supported_parameters=tools`) are specific to
+  OpenRouter/Anthropic. MinerU, Whisper, and future OCR/ASR services have
+  different auth shapes (an API token, optionally a project id) and no
+  `/v1/models` endpoint.
+- Its uniqueness key is `(organizationId, providerId)` where `providerId`
+  is an OpenRouter-style model-routing id. A capability provider id
+  (`mineru`) names a *service*, not a model.
+- Coupling capability credentials into the model-provider table would force
+  every capability's auth shape through `ProviderSecretPayloadV1` and every
+  readiness probe through `probeOpenRouterCredential`.
+
+The Feishu Application Connection (`OrganizationFeishuApplicationConnection`)
+is the right structural precedent: it reuses the ADR-0024 envelope (KEK →
+DEK → AES-256-GCM, AAD-bound to purpose/org/connection/version) but has its
+own connection table, its own payload schema, its own readiness probe, and
+its own per-org uniqueness. Capability connections follow the same pattern.
+
+## Decision
+
+### External Capability
+
+An **External Capability** is a platform-registered, org-enabled document or
+media transform service invoked as a side effect of an `AgentRun`. It is
+identified by a stable `capabilityId` (e.g. `pdf_to_md_bundle`,
+`audio_video_to_text`). A capability:
+
+- Has an **input kind** (PDF, image, audio, video, …) and an **output
+  contract** (markdown bundle with extracted images, transcript text, …).
+- Bills in **non-token units** (pages, audio-seconds) recorded on a
+  `UsageFact` with `kind = external_capability`, or in tokens when the
+  backing service reports them.
+- Writes its output **into the invoking run's workspace** (ADR-0018
+  `AgentSurface` — no escapes).
+- Is invoked through a **capability adapter** in Hub, never by the Agent
+  shelling out with embedded credentials.
+
+### Capability Connection
+
+Credentials for a capability live in an **`OrganizationCapabilityConnection`**,
+structurally identical to the Feishu Application Connection:
+
+- Belongs to exactly one Organization.
+- Unique by `(organizationId, capabilityId)`.
+- `DRAFT` / `ACTIVE` / `DISABLED`; resolution accepts only `ACTIVE` with a
+  valid active secret version.
+- Secret material is an immutable, AAD-bound, KEK-wrapped envelope version
+  (`CapabilityCredentialVersion`), reusing the ADR-0024 encryption
+  machinery with `purpose = "capability"`.
+- Its payload schema is capability-specific (`CapabilitySecretPayloadV1`:
+  `baseUrl`, `apiToken`, optional `projectId`). New capability types extend
+  the payload, not the connection table.
+- A capability-specific **readiness probe** validates the credential before
+  activation (e.g. MinerU: a trivial authenticated GET). The probe is
+  injectable, matching the Feishu/provider pattern, so tests never hit the
+  network.
+
+### Capability Adapter
+
+The adapter is the seam between the Agent and the external service. It:
+
+- Resolves the org's active capability connection (fail-closed, no
+  process-global fallback — ADR-0024).
+- Accepts a workspace-relative input path and an output directory.
+- Calls the backing service (MinerU, Whisper, …) via an injectable
+  `Client` interface so the real HTTP client is swappable and mockable.
+- Writes the produced markdown + image assets into the run's workspace.
+- Writes one `UsageFact` (or more, if the service reports per-stage
+  consumption) with `kind = external_capability`, `capabilityId`,
+  `provider` (the service id), `quantity + unit` (pages / seconds), and
+  `costUsd + costSource = provider_reported` when the service reports cost.
+
+### Registry
+
+The platform maintains a **registry** of known capabilities: their id,
+input kind, output contract, metering unit, and adapter. This is
+code-level registration (like `ToolRegistry`), not a database table — a
+capability is available to an Organization only when (a) the platform
+knows the adapter and (b) the Organization has an `ACTIVE` connection for
+it. Both gates are required.
+
+### What is NOT in this ADR
+
+- The capability invocation is **not** a first-class persisted record
+  (`CapabilityInvocation` table) in this ADR. The `UsageFact` row with
+  `capabilityId` + `correlationId` is the durable trace. If we later need
+  a richer invocation log (retries, partial output, multi-stage status),
+  that is a follow-up; for now the fact is enough.
+- **Pricebook** remains deferred (ADR-0026). Capability facts use
+  `provider_reported` when the service returns cost; otherwise `unknown`.
+- **Org-scoped enable/disable policy** beyond connection status is
+  deferred. An org with an `ACTIVE` connection has the capability; one
+  without does not. A finer "enabled but no credential" toggle is not
+  needed yet.
+- **Agent-facing tool exposure** (how the Agent discovers and calls the
+  capability — MCP tool, Bash wrapper, or built-in) is an implementation
+  detail of the adapter wiring, not a contract concern. The contract pins
+  that the Agent never receives the capability credential.
+
+## Consequences
+
+- Adding a new external capability (e.g. `image_ocr`) is: register an
+  adapter, add a `capabilityId` constant, optionally extend the secret
+  payload — no schema change to `UsageFact` or `AgentRun`.
+- The model-provider connection table stays focused on model routing;
+  capability credentials do not pollute its payload or readiness probe.
+- Three connection types now share the ADR-0024 envelope: model-provider,
+  Feishu application, and capability. Each has its own table, payload
+  schema, and probe, but the same encryption, rotation, and resolver
+  boundary.
+- The Agent's Bash tool remains available, but the intended path for
+  document/media transforms is the capability adapter. Whether to narrow
+  Bash for capability-shaped tasks is an operational policy decision,
+  not a contract one.
+- Tests prove: workspace containment of capability output, fail-closed
+  credential resolution, `UsageFact` attribution with non-token metering,
+  and that the Agent process never receives the capability credential.
+
+## Deferred
+
+- `CapabilityInvocation` as a first-class durable record (status, retries,
+  partial output) — currently the `UsageFact` row is the only trace.
+- Pricebook derivation for capability costs (ADR-0026 deferred).
+- Org-scoped capability enable/disable policy finer than connection status.
+- Agent-facing tool discovery (MCP vs built-in) for capabilities.

+description: >
+  Convert PDF documents to Markdown bundles using the convert_pdf_to_md tool.
+  Handles PDFs from Feishu messages, local workspace files, and produces
+  high-quality Markdown with LaTeX formulas and extracted images.
+---
+
+# PDF to Markdown Conversion
+
+## When to use
+
+Use this skill when the user asks to convert a PDF to Markdown, extract text
+from a PDF, or turn a PDF document into an editable format.
+
+## How it works
+
+The `convert_pdf_to_md` tool (provided by the `cph_hub` MCP server) calls
+Alibaba Cloud Document Mind to parse the PDF. It:
+
+- Extracts text in reading order (handles multi-column, scanned, and
+  multi-language documents)
+- Converts mathematical formulas to **LaTeX** (`$...$` inline, `$$...$$` block)
+- Extracts tables as Markdown tables
+- Downloads embedded images into the output directory
+- Writes a single `document.md` file plus image files
+
+## Workflow
+
+### PDF from a Feishu message
+
+1. Use `feishu_read_context` to find the `file_key` of the PDF attachment.
+2. Use `feishu_download_resource` to download it into the workspace.
+3. Use `convert_pdf_to_md` with the downloaded file path and an output directory.
+
+### PDF already in the workspace
+
+1. Use `convert_pdf_to_md` directly with the file path and an output directory.
+
+## Important rules
+
+- **Always** use `convert_pdf_to_md` for PDF→Markdown. Do NOT attempt to parse
+  PDFs yourself with Read, Bash, Python, or any other method. The tool provides
+  accurate formula, table, and image extraction that manual methods cannot
+  match.
+- If `convert_pdf_to_md` fails because no capability connection is configured,
+  tell the user to ask their organization admin to configure the Aliyun
+  docmind credential in the admin web UI (组织后台 → 能力).
+- The output directory will be created if it does not exist.
+- After conversion, use `send_file` to send the generated markdown back to the
+  user if they requested it.
+
+## Output
+
+The tool returns a list of generated files:
+- `document.md` — the main markdown file
+- `*.jpg` / `*.png` — extracted images, referenced from the markdown
+
+## Cost
+
+The conversion is billed per page (0.04 CNY/page ≈ $0.0056/page for the
+enhanced formula mode). The cost is automatically recorded on the run's
+usage ledger.

-# spec —— Lean 语义母本
-
-这是本 monorepo 的**契约**:产品各部件语义的上游参照,用 Lean 编写。它的定位与约束见仓库根 `README.md` 的"宪法"5 条——本文件只讲**怎么往这份契约里写东西**。
-
-## 现状
-
-刚初始化的 Lean 工程(`lake init`),目前只有占位内容(`Spec/Basic.lean`)。实质领域内容(System 平台层、Courseware 产品层)将逐个概念加入,每个都遵循下面的规范。
-
-## 构建
-
-```sh
-cd spec
-lake build
-```
-
-工具链锁定在 `lean-toolchain`(`leanprover/lean4:v4.31.0`)。无外部依赖——Mathlib / Batteries 等留待第一个真正需要它的定理出现时再引入(依赖碰到再加)。
-
-## 写作规范
-
-### 双半契约:prose + type
-
-每个 top-level 声明**必须**带 `/-- … -/` doc 注释,用自然语言陈述其语义意图。两半缺一不可:
-
-- **prose 半**给人读——说清"这在领域里是什么、为什么"。
-- **type 半**给机器读、给 type checker 把关——保证结构无洞。
-
-agent 不得用预训练先验脑补本领域(领域很新,无先验);prose 是 agent 理解语义的唯一权威来源。
-
-### 标签分类法
-
-在 doc 注释里用以下标签标注每条语义的状态:
-
-- **`PINNED`** —— 已解决的分歧点,契约在此处权威,双方据此对齐。
-- **`OPEN`** —— 故意未规定。双方均**不得假设**其解;实现遇到时必须 surface 出来讨论,而不是擅自决定。
-- **`ADR-NNNN`** —— 链接到根 `docs/adr/` 下的对应决策记录(如 `ADR-0002`),交代该语义的决策出处。
-
-### 分歧点测试(写之前先过一遍)
-
-新增任何概念前,先问:**"不写明,开发者与 agent 会不会各自做出不同假设?"**
-
-- 会 → 它是分歧点,入契约。
-- 不会(显然的东西 / 纯 plumbing / 普通 CRUD 字段)→ 不入。
-
-详见根 README 宪法第 5 条。
-
-### 不用 `sorry`
-
-无法陈述清楚的东西,用 `OPEN` 在 prose 里标注,而**不是**用 `sorry` 留一个假装成立的定理。`sorry` 会让 `lake build` 仍然变绿,却在契约里埋一个谎——这与"契约自包含、无洞"直接冲突。
-
-### 命名
-
-- **模块 / 命名空间**:PascalCase,对应分层,如 `Spec.System.Agent.Run`、`Spec.Courseware.Validity`。
-- **类型**:PascalCase。
-- **谓词 / `Prop`**:用意图清晰的命名,如 `Legal…`、`ValidTransition`、`Can…`。
-- **文件粒度**:原则上"一个带独立不变式的概念一个文件"。

-- `Organization` —— SaaS 租户(ADR-0020);project/team 单归属,TEAM grant 不跨 org;
-  connection secret 信封与 fail-closed resolver(ADR-0024);
-  owner/admin/member(`OrganizationRole`)及其管理规则(最后所有者保护)。
-- `ProjectWorkspace` —— org 后台 project explorer:folder 是透明组织节点,project 仍是权限边界
-  (ADR-0021)。
-- `Capacity` —— platform ceiling 与 org policy 的分层限制、持久 admission request 状态和
-  平台紧急工作负载制动(ADR-0022)。
-- `PlatformAdministration` —— 独立平台身份/会话、单一管理员角色、绑定邀请、最后管理员
-  保护、fail-closed 平台审计与离线 emergency grant(ADR-0023)。
-- `AgentRole` —— org-scoped agent 角色配置 + 技能(ADR-0017/0018)。
-- `Run` —— AgentRun 状态与终止判定(状态集合完整性 OPEN)。
-- `Lock` —— 锁 owner=run(ADR-0002),及"持锁者必为非终止 run"的核心不变式。
-- `Memory` —— 按需上下文:锚点类别(ADR-0003)+ MCP 工具按 run/project 上下文授权。
-- `AgentSurface` —— agent 执行面被 run 的工作区所界定(ADR-0018);与 Lock 正交——
